Indeed, the latter is already available in V.4 via the F_FREESP command
to fcntl(), which allows you to punch holes of arbitrary size at
arbitrary locations in a file. Undocumented and so far unimplemented,
but hinted at in the code, is the corresponding F_ALLOCSP command that
would allow the opposite. Neither F_FREESP or F_ALLOCSP appear yet in
the SVID or any other standard, but we can hope that they (or
equivalent functionality) will eventually be standardized.
