| Choice #2: use $'...' quoting,

No it isn't, or at least not any more. Dollar-Quote quoting (sometimes
called C-stye strings) is in the latest POSIX standard.
I'm not sure of its origins (it was proposed to POSIX decades ago),
Chet can confirm, but I suspect bash picked it up from the proposal
to POSIX.
This form of quoting will be found in any shell claiming to be even
close to up to date now (but beware of using it outside what is specified
to work, once you go there, behaviours are not identical).
