Well, if you enforce to implement the old POSIX behavior, you get what the old
POSIX definition says: timing is only possible for external commands.
If you use the extension, you get more....

Given that mksh claims to emulate ksh88 and sometimes ksh93, it could be seen
as a bug.

BTW: I remember that you frequently write that zsh intends to emulate the csh
behavior, but csh _is_ able to get timing for builtin commands:
csh
% time alias
0.0u 0.0s 0:00 0% 0+0k 0+0io 0pf+0w
