I feel like the current RFC text is very biased in favor of adding the 
alias. I believe it would be prudent to also list possible caveats and 
arguments against so that voters are able to make an educated decision. 
Several points have already been raised in the pre-RFC discussion 
thread, for example the possible confusion with `str_split()`.

While it's not strictly necessary to follow the RFC template, it is 
often a good idea to make sure everything is accounted for. The template 
specifically contains an RFC impact section that is missing from your 
RFC: https://wiki.php.net/rfc/template#rfc_impact.

The “Backwards Incompatible Changes” section should also mention that 
`split()` would no longer be available to userland. Quoting from the 
template:

>  Please include all breaking changes, no matter how minor they might 
> appear. All research you did on potential impact should be listed in 
> this section.

and
