Ivan Mincik (imincik): when you have build failure on dependant packages (like for geopandas), do you fix them in the same PR? Or do you open subsequent PRs?

Can be fixed in the same PR or in a new one. Doesn't matter too much. If you personally want to fix some of failures reported in geopandas PR it might be better to open a new PR rather then pushing in PR created by me.

We also ignore failures if we know that they are not caused by current PR. For example, packages like bsuite or plotnine are broken very often because of something else.
