Interesting indeed. Seems like you have had project-switch-commands set 
to the "new format" value (because of the var autoload, probably), but 
were using the older code with it.

Another piece of the puzzle is that GNU ELPA is still on version 0.5.3, 
whileas the version bump to 0.5.4 was made around 2021-01-28, which 
should have triggered the new release.
