As someone who loads extra layouts just in case, I find the reverse
order switching to be invaluable.

I use lctrl+rctlr; it may be easier to deal with the reverse order
in such cases than with the shift+alt type of combination. But I
almost always “go back the way I came” when switching between my
layouts.

I would hate to loose that capability.

I would not, however, object to having to change my config to explicitly
specify that I prefer the non-commutable behaviour, should commutable
become the default.
