I'll take you up on that one, Smithsax. I've been doing Listeners for about 25 years, and in the last ten I've hardly missed one (except the numericals). I solve them much faster, on average, than I did when I started, but that's not surprising as I like to think I've got better at solving crossword clues over the years. There would be something wrong if that wasn't the case! So I'm not really in a position to judge whether the clueing side of things has got easier in recent years, though my gut feeling is that it hasn't.
However I would say that on the thematic side, there has been a gradual shift towards simpler implementations of themes. I couldn't track down the Dimitry puzzle mentioned earlier on this thread, but I found the solution notes on the Listener site and just reading those was enough to me have to go and lie down. If memory serves (and I can't count on that) there were far more puzzles back then which required complicated manoeuvres to fill the grid than there are now. The only two which belonged to that category last year were those by Sabre and Harribobs (both of which got a lukewarm reception here and elsewhere). The norm for puzzles in recent times is for a relatively straightforward method of entering answers, and any stumbling blocks tend to be in the form of a leap of faith in the endgame (such as the bee colony puzzle and the recent Elgin, which is still live.
Personally I don't mind the increase of "entry-level" puzzles; I've reached a point in life when even in lockdown I don't want to spend hours on one puzzle every week. That won't be a popular view, and I can understand that. I agree with Malone (as I invariably do) at 29 that there's nothing wrong with posters expressing disappointment at a lack of challenge, but at the same time I think we should be careful of being too dismissive to avoid putting new solvers off coming to this forum.
Apologies for even worse long-windedness than usual.
