Amen.  Or, as the saying goes:

"All prognoses are hard, even more so those concerning the future."

(Made famous by Niels Bohr, but may have been a widely known in his home 
country of Denmark before that).

Let's face it: unless you're a major customer (and no, an order volume 
of a million units does not reliably make you one), any and all 
expectations about parts availability in the micro controller market 
that reach further than a few months into the future are recklessly 
optimistic.  And that was how it was _before_ the pandemic and all its 
side effects.

If you need to be sure you have those chips in quantity x over the run 
of a given product, and x has fewer than 7 digits, your only truly safe 
bet is to stockpile the whole lot up front.  The next-safest plan would 
be to stockpile enough of them to tide you over the conservatively 
estimated time for a redesign of the board and most of the lower-level 
software.  Obviously neither of those options is cheap; but the main 
alternative is that you may one day have to discontinue your whole 
product because that one part suddenly turned into unobtainium.
