> it’s a waste of resources for seniors to be doing the work that the juniors and 2s can do. Hunting down infrequent or low priority bugs, fixing small layout issues, etc.

These are tasks that in the current environment often get pushed back for "later" indefinitely. These tasks aren't un-resourced because the company isn't hiring juniors, the company isn't hiring juniors because they no longer have the funds for small fixes.
