For what it's worth, I sympathize and kind of agree with the OP, but...
I also find myself disoriented and curious. Did the great board crash throw us all into a time warp back 15 years or so? Because the complaints of this thread (no shorter adventure modules, fast leveling of modern D&D) are not at all new or unique to 5e, but are characteristic of the D&D market for the entire 21st century, if not before that. These exact same issues were brought up when 3e came out, lo, these many years ago.
True, There was not the focus on Campaign spanning 'adventure paths' (Pazio had not pioneered the method yet as a way to profitably make and sell adventures), and WOTC did have some shorter adventures to 'showcase' the new edition, but these were more loss leaders designed to sell PHBs and such, rather than bread and butter products. .
You have an unusual idea of "some".

Even 4e had 20 adventures in the first 2 years it was out, and only
one of those was for an entire level range (dungeon delve, 1-30). So no, I don't agree that this is the same situation that's been going on for 15 years. The numbers clearly show otherwise.
