I'm not a fan of reading the full key sequence bypassing the event loop.

'C-h' can't work since 'C-x p p' is bound to a command.

I guess there could be 2 new alternative options for 'project-switch-commands':

1. read the full key sequence
2. use the event loop with set-transient-map

Although I'm already completely content with the existing option
'project-prefix-or-any-command' of 'project-switch-commands'.
