@s2b Can you please:

• Add some more description to the pull-request
• Add some commit message describing it
• or at least add and reference an issue

There is nothing which can be read why what is expected
and why this should be considered as bug. Especially why
the chosen solution is the correct way o fix it. Or
better to say why the behaviour should be the expected
behaviour.

Just from the code, I'm not quite sure if everyone would
follow what you postulated by code here and why it is fixed
the way you do it.

Not sure if this this is really a bug or more a feature.

It's debatable if a later re-announcing a already added
path should change the order. It may be your use-case,
but is it really a valid expectation in all cases ?

This is a drastically change in behaviour. Could be that
this should be handled more by the consumer to deside
how to merge multiple ways of path configurations ?

Sorry, this was meant as a draft to check if this fixes https://forge.typo3.org/issues/81099. I‘ll add more information later.

This has been fixed in TYPO3 now, so this is no longer relevant
