I dislike convention-based naming, like ZF1 used to do everywhere. However, this seems like indeed an unnecessary BC break, which is also hard to discover. I feel like the risk outweighs the benefits.

I explicitly set all my routes with FQCN like this: #[Route('/', name: self::class)] to avoid managing arbitrary strings.

I agree with Anna of.

Another idea: {% if 'App\Controller\MyController' == app.current_route %} could be turned into something like {% if is_current_route('App\Controller\MyController') %} or similar, WDYT?

I agree with Anna too.

Another idea: {% if app.is_current_route('App\Controller\MyController') %} and check against both name and alias.

Thank you for this suggestion.
