Yeah, that is the current state.

You can have two different SelectFeature controls attached to the map;
the problem them is switching between them becomes a deliberate user
action.

You can also collect click events explicitly with a Click Handler, and
on a click, loop through your non-active select layer, and test for
Geometry intersection. This would essentially mimic the way that I would
advise building a more advanced SelectFeature that supported selecting
features from multiple layers.

Yep, that's what I would recommend.
