I initially hesitated to support the drop of
nth_midxed_pack_entry(), since it was designed with things
like midx bitmaps in mind (specifically, to also support
lex-order-to-stable-order conversions).

I didn't know that nth_midxed_pack_entry was designed with either
purpose in mind, since it predates midx bitmaps by quite a bit.

Thinking on it more, I can imagine that you wrote this function
aspirationally envisioning something like MIDX bitmaps. And since you
and I discussed the design together quite a bit, I imagine that that's
the case ;-).

But I agree that after reading this series again, that the inline-ing
suggested makes sense (and doesn't conflict with any series I have in
flight which don't add any new callers).

I'm thinking more to my original design of the multi-pack-index.
At that time, I was thinking about the possible integration
with bitmaps based on my experience in other systems which used
a stable object order to allow writing bitmaps asynchronously
with respect to the multi-pack-index write and object packing.

One thing that you did when first considering bitmaps over the
multi-pack-index was to demonstrate that a stable object order
is not required, which surprised and delighted me. It greatly
reduced the complexity of the problem, and being able to inline
this method is only one small fallout from that simplicity.
