although this makes sense, it'd conflict with the performance API that comes next, since this field kinda got changed, let's not merge for now

[ueman]

@marandaneto Should this still be considered or can this be closed?

I mean it kinda makes sense if performance tracing is disabled.

[marandaneto]

we can make a fixture

[marandaneto]

we can make it private and probably give a better naming, also writing in the ctor docs that enabling this overwrites the current transaction name in the scope.

about the name, maybe routeNameAsTransactionName not sure, but setTransaction only is too subjective IMO

[ueman]

This can't be made private because it's a named constructor argument. Though because it's final it's basically readonly.

still makes sense, I did a review, would u like to work on it? so we can merge, thanks for doing this btw.

[ueman]

What should happen if the route name is null?
Resetting the transaction name to null or just nothing?

[marandaneto]

nothing I'd say, but I guess the route is never null anyway

[ueman]

Closed this in favor of #615 because I don't have the rights anymore.
