Can we merge this?

Looks good to me, thanks for your contribution!

If you want to have it immediately published, you can target the latest release/2.6 branch instead of develop2, then it will go live without having to wait until the next release (develop2 is the default for new features to be in the next release)

Do I need to rebase or Github will handle the branch change?

It's ok, the two branches have not diverged yet so merging in 2.6 does not require extra changes on your part :)

The CI is currently failing with

Warning, treated as error:

conan/tools/qbs/qbs.py:docstring of conan.tools.qbs.qbs.Qbs:6:Field list ends without a blank line; unexpected unindent.```

Apparently, conan-io/conan@369a3d0 is not in 2.6 branch

[ABBAPOH]

Can I cherry-pick to 2.6 conan-io/conan#16821 ?

@ABBAPOH thanks for the contribution, it will be published in a couple of minutes when the ci job ends.
