[Maxima] .mac ? why

[Yigal Weinstein]

Is the file extension .mac the only extension for Maxima?  I ask because
if it is isn't it time to change .mac -> .max ?  Anyone downloading who
can read realizes that Maxima came from a program Macsyma, but Maxima
has evolved into its own creation and should have its own file
extension - no?  I thought a rather superficial question would make my
life a little fun. Are there problems with some of the legacy code not
be free so .mac is needed for this stuff or what?

Thanks for indulging me.
