Hmmmmm, I'm not sure if I understand you, probably because I'm not awake enough yet. Even if 42 programmers use `internal_delay()`, you still need to account for the two programmers (ch341a_spi, serprog) using a different function. So, unless you need to change things regarding `struct programmer_entry` to get rid of the `programmer` global handle, this change shouldn't make the removal easier.

TL;DR: I'm OK with this change, I just don't understand how it would have an effect on the removal of the `programmer` global handle.
