There should be some way to "grandfather in" the old default, while
migrating towards a new setting.  Consider the comparison case:
mainstream window managers provide locale-based configurations. EN_US
might be the universal default, but it is easy enough for system
admins to change this to various other standard settings, even that's
just EN_UK.

How about adding a configuration-time flag with a name that would help
people see that C-a is less-than-optimal, e.g.:

LEGACYCOMMANDKEY: set the command to C-a (this could still be the default)
MODERNCOMMANDKEY: set the command to some as-yet-unspecified saner command
