Ben, Matthew, Moritz, and friends

Is this wiki page about architectures still accurate?

For example, ARM is not Tier 1, or "apple silicon".

Yet I know some of our developers have invested lots of effort in other architectures, so maybe those efforts are not reflected here.

Relevant is Moritz's post about 32-bit architectures.

We should in due course add Javascript and Web Assembly as Tier 1 back ends?

Are we saying "if your customer bases uses Tier 2 architectures, you can't rely on GHC from one release to the next"?  I wonder if there are companies for which Tier-2 architectures are mission-critical.  Mis-aligned expectations cause upset.

I mention all this because it is relevant to our stability guarantees.  Every time we release we should point to this list.
