I feel changing the name around by a single persons preferences is not
really a nice thing to do community-wise. So I'd like to hear other
people chime in first before I make that change.

I don't think the name is hugely critical (but it's always the hardest
to settle on). My preference order would be:

taskfd_send_signal()
pidfd_send_signal()
procfd_send_signal()
fd_send_signal()

imo, either procfd_send_signal() or taskfd_send_signal()

It seems to me that using flags later to specify sending to pgrp vs thread
is fine:  it's specifying how to interpret the 'fd' in 'procfd_send_signal()'.

But, agreed, I think fdkill() should not be used.
