Well there is one fact totally overlooked in this whole thread:
Check out the (officially supported) D&D Computer Games:
Most of them have magic item Shops:
1st and 2nd ed
All of the infinity engine (Baldurs gate IWD Planescape etc.)
Both Dark sun games
Some Gold box games
3E
Neverwinter nights
The MMORPGs
3.5E
DDO
(based on 4E)
Neverwinter
Even the latest Thing with 5E like rules i cannot recall the Name sword coast legends it is i think. It is bugged with a grafic error since it last update making the game no big fun to Play but it has magic item Shops all over the place.
Those D&D games that did not have Shops are the eye of the beholder series, Both ravenloft and Menzoberranzan, all 2nd ed.
So it is not to far fetched to say:
Even if Pen and paper modules never supported the Shops that much,
there is no official saying that Magic item shops an absolute nono in D&D, en contraire they are featured in many of the CRPGs
