There already is something to switch to - the "{$foo}" syntax (which is 
staying) supports everything the "${foo}" syntax does and more. There 
has been intermittent talk of adding "even better" interpolation of some 
sort, but without consensus on exactly what the features should be - 
search on https://externals.io/ to see previous threads.

(And yes, PHP does have a "goofy" use for backtick, inherited from Perl, 
as an alias for shell_exec. But that's not really relevant because there 
are plenty of programming languages which have multiple quoting styles 
without using it, mostly by adding a prefix, e.g. Python's f"...".)
