PERF: maybe_convert_objects convert_numeric=False
I think this fixes a perf regression that @phofl pinged me about a few weeks/months ago, but I forget the details.
maybe merge? Can't remember anymore either Explode? Ah explode might be the culprit, yes couple of failing tests thx @jbrockmendel (accidentally pressed the wrong button...)

Lets see how this changes our asvs, if we see a regression fix then can backport? works for me Looks like it's worth backporting
