@TheDroid,
I agree with your considerations and I think that anyone who wants to talk about inner sleeves could take a look or contribute in 45spaces/Company Sleeves:Lp perhaps making a reference in the comments.
If I'm sure that the inner sleeve is authentic I usually add it, sometimes this is hidden like here , that's fine too.
@robozuc - the real problem with relying on posted images of inner sleeves to determine completeness is that there is little or no assurance that the pictures sleeve was in the original packaging. There is also seldom any way to determine if a particular generic sleeve is associated with a particular album/LP. If there is a way to determine this (ie. Catalog #), then, of course, it should be included. With the proliferation of used record stores over the past 50-60 years, many sleeves have been changed in packaging, often with no care to even the label.

Personally I believe that being able to see the inner sleeves, even if generic, helps the collector to have a complete vision of the disc, the value can change depending on the completeness of the item.
But this is my personal opinion.
Some pressings list the album title as “Alone At Last” on the record label. Other pressings simply give the title as “Denny Doherty”, again just on the label.
Added promotional label set pressed by Monarch Records, Los Angeles, CA. Hand etched in the deadwax on side two is "with love from Jessica". The deltas for this are:
Side One Δ 15551.
Side Two Δ 15551-X.
