This PR:

Replaces abandoned webmozart/path-util with symfony/filesystem.

Fixes #1634

[martinssipenko]

I just noticed the conversation in #1634 about dropping Symfony below 5.4. Question I have is why do you need to keep those old Symfony versions?

[maks-rafalko]

I think we don't need it.

All the versions below 5.4 EOLd (ok, except 4.4), so personally I'm ok with the current state of this PR.

Users with older SF versions will use Infection <= 0.26.10

[martinssipenko]

@maks-rafalko dunno whether 4.4 works on PHP 8.0, which is required for Infection. Will you merge the PR then? I later can follow up with another one to remove < 5.4 altogether.

[maks-rafalko]

dunno whether 4.4 works on PHP 8.0

according to symfony repostiories and GH Actions, it works even on 8.1

Will you merge the PR then?

yes, right now

I later can follow up with another one to remove < 5.4 altogether.

do you think it's needed? for what reason?
