This is also the way I use YouTube and is the main thing I made Control Panel for YouTube [1] for (well, that plus globally hiding Shorts and removing all the unwanted recommendations everywhere) - my Subscriptions page acts like an inbox of unwatched videos and everything else is hidden (most recently: the new "Most relevant" section and "Collaborations" videos with channels I'm not subscribed to).

My Subscriptions page currently has 15 videos above the fold, 5 of which are from the last 12 hours. The oldest video in that first page is 2 weeks old, and if I turn the extension off I need to press Page Down 17 times to reach it in the vanilla YouTube interface.
