I don't agree. It makes perfect sense for the Tiefling entry to say they're common in Sigil, just as it makes perfect sense for the Minotaur entry to say they're common in Krynn.
Not really. Setting specific stuff can be saved for the settings themselves. There's only so much space in the books, and putting in obscure lore only means less space for more important stuff. And it's worse if the people who want to play Planscape or Dragonlance or any of the other classic settings don't want to move up to a new edition and play with older rules.
I'm not sure whether this has been mentioned upthread, but the Blood War was actually introduced in MC 8 The Outer Planes Monstrous Compendium Appendix, not Planescape, and that's also when names like baatezu, tanar'ri and yugoloth first appeared too.
It's possible that people forgot it because the MC format wasn't exactly well loved and MC 8 was later replaced by the first Planescape MC, which became the offical source for these creatures.
But, honestly, for me, this was the beginning of the end for planar material in AD&D. After this, it was all Planescape all the time and you couldn't swing a dead cat without Planescape lore infesting every bloody book.
3e was a huge breath of fresh air for me. Finally most of the planar stuff was stuffed back into some source books that I was free to ignore.
As I said over in the related thread, I blame this one on TSR's obsession with campaign settings. From 1994 to 1998 you couldn't have generic, core planar references, everything had to be Planescape to pimp the line. But it's generally agreed that this whole approach divided the D&D player base and ended up losing money for TSR. Then WotC bought TSR, and made the somewhat wiser decision that this stuff really should be folded back into core. Unfortunately, the Planescape fans weren't happy that their favorite setting had been discontinued, just as fans of the other settings were similarly diappointed. As this and the other topic show, the division is still showing its effects.
3e's approach wasn't too bad. The early material didn't mention Planescape at all, except for the MotP which of course gave a brief mention of Sigil and some various bits of fluff here and there from the setting. It didn't need to reprint most of the fluff and MotP has most of what a DM needs mechanically to convert a PS campaign up to 3e. For those who don't want PS, the book is presented as a collection of options and ideas, so the PS stuff can be ignored.
