Any objections to merging this? Not sure how coverage dropped 0.1%

I don't know if there should be any rules for "don't merge your own PR" or "must require a review."

I'd like to add phpstan in another PR, but need to touch composer again.

I personally wasn't sure if this PR was ready for review or was still a WIP. I'd favor having a general policy that at least one other person review/approve a PR but I think it's totally fine to merge your PR once it's gotten feedback from at least one other person. We could also make use of requesting reviews from other maintainers or a team.

One thing I noted after my review: the line in CHANGELOG.md mentioning the raise to 7.1 for 2.0.0 should be adjusted.

Not sure how coverage dropped 0.1%

It's related to line 323 in vfsStream.php - I don't even know why this line was previously reported as covered.

So I'd say go ahead and merge.
