Some notes I was writing at #12008 before I realised this issue existed:

• Particular focus on what is currently provided by Boost today.
• Possibly moving some functionality into lotus-shed for convenience.
• Taking careful note of builtin actors testing that will be removed in the process so we can restore some kind of coverage via alternate means.
• Clear documentation of what's changing for downstream users.
