To clarify, this is handled automatically when consuming messenger messages, correct?

[Seldaek]

Yes I believe so as of https://github.com/symfony/symfony/pull/40761

@GromNaN as early reviewer, do you see something else to add on this PR? thank you

[GromNaN]

All good. I'm wondering why this is not automatic.

[OskarStark]

Should be against 4.4

[94noni]

@OskarStark fair enough, will handle it soon :) thx @GromNaN for answer

[94noni]
