My update does check the available CRS from GetCapabilities for each layer
and will flag a layer as unusable if it doesn't match the current projection
set in JOSM's preferences.

I like your idea better, though: prompt the user to change the projection so
that it matches the projection of the selected layer(s). Right now it would
only support switching to 4326 I suppose, but in the future it could switch
to other JOSM-supported projections. Is there a preferred method to call to
set projection (so that the GUI is updated after the change)?
