as it's easier to deal with TSAN false positives in the former API
as surfaced in PR 280 the current supression rules don't handle newer versions of the
scoped_threadpool crate
trying to update the supression rules related to scoped_threadpool in PR #282 revealed that the
supression rules are masking (hiding) real data races:
https://github.com/japaric/heapless/pull/282#issuecomment-1113173358
std:🧵:scope requires less supression rules and does not mask real data races -- for instance,
the data race in the linked issue comment is not masked when using std:🧵:scope
tradeoffs:
- pro: one less dev dependency
- pro: supressions file is simpler
- cons: std:🧵:scope is only available on recent nightlies
