upon the first occasion we need to fix this block, let's move it into some tools/ci/check_schemata_no_changes helper or alike

[yarikoptic]

Initial pass

👍

fold versioneer fixing (#19 ) in here so we get a green light (I guess it is what trips pull_requests with known to us error message) ... if something else -- needs to be fixed up too I guess

[jwodder]

@yarikoptic Do you mean that you want #19 to be part of this PR instead of a separate PR?

@yarikoptic Do you mean that you want #19 to be part of this PR instead of a separate PR?

that was my thinking since fixing outside would not be CI-tested. but I will leave it up to you -- can leave #19 on its own and merge, and rerun tests here

[yarikoptic]

woohoo -- all green and coverage improved! Let's proceed. Thank you @jwodder !
