It's a pity to think just how fitting a venue Le Stadium would have been for Sunday's European quarter-final.
When compared to the impact the coronavirus has had upon almost every aspect of everyday life, it goes without saying that the switching of grounds for a rugby game is relatively trivial but it's nonetheless a reminder of the occasion this was set to be.
Before the pandemic struck, for Toulouse to have been hosting Ulster in April and bringing the game to the usual home of the Pink City's football team, a venue primed to be turned into a sea of rouge et noir by 37,000 locals, would have represented their resurgence in a way the 5,000 socially-distanced souls set for the Stade Ernest-Wallon this weekend never will.
To think of Stade Toulousain in weeks such as these is to think of Emile Ntamack, Clément Poitrenaud, Vincent Clerc and Yannick Jauzion, the old European artisans and their extraordinary run of five finals and three wins in the space of just eight years.
Big days at Le Stadium were a regular occurrence during those glory years, the intimidating amphitheatre playing host to 11 European knockouts over the years with Leinster's 2006 quarter-final triumph the only away victory.
Toulouse would get their revenge over their fellow four-time winners of the competition in 2010, dethroning the then European champions in the semi-finals of that year's competition.
That was the last time an occasion merited bringing a game to their home away from home, the decade-long break from hosting European knockout games reflective of how the one-time standard bearers had fallen from grace.
Come Sunday afternoon, Ulster will have played only Stade Francais more often in this competition. The classic, at least in this part of the world, is undoubtedly the quarter of 1999, a game that would have taken place in Le Stadium rather than the sideways rain of Ravenhill if not for Toulouse inexplicably losing to Ebbw Vale in the final pool tie.
Perhaps the most jarring, though, was their visit to Belfast in the winter of 2015.
There were still a sprinkling of those with multiple medals hanging around their necks, and plenty of French internationals too, but few visiting sides have looked less interested to be in Belfast than Toulouse did that night.
They were duly spanked, the five-try, 38-0 romp enjoyed by Les Kiss' men proving to say much more about the opposition than the direction of the northern province. It was the first time Toulouse had been nilled in Europe, and they showed considerably more fight at home a week later - in the sense it was more than zero - but Ulster ran out winners again.
After finishing bottom of a pool that contained soon-to-be relegated Top 14 rivals Oyonnax, they soon sunk even lower by failing to qualify for Europe's top competition for the first time in their history in 2017.
That year in the Challenge Cup, the cavalry was on the way. Romain Ntamack made his European debut, so too Cheslin Kolbe and Thomas Ramos.
It was players like these, along with signings such as Jerome Kaino, Rory Arnold and Charlie Faumuina, that formed the spine of the team that just one season later would win the Top 14, the Bouclier de Brennus representing a first trophy since 2012.
Since emerging from lockdown, joyous tries ran in from all angles and distances lead to the unavoidable conclusion that Toulouse are back... even if they're not back at Le Stadium quite yet.
