I know this is an old subject, as this has been stated in the struct reference
page ever since D1, but I'm really wondering why the bit fields aren't
supported (or purposely not implemented?) in D.

Having this feature would greatly simplify a lot of code, and allow easier
interfacing with C structs using it.

It actually wouldn't, since C doesn't specify any order to packing
bitfields, whether there should be padding etc.

In D2 it is supported by phobos:

Google is your friend.  This thread has happened at least once in the past
already.  Before rehashing it, might as well catch up on the past discussion:
