Guidance around use of <input> types

Hello,
The native input types in browsers still all seem to use the OS locale.
Looked like Chromium talked about fixing this (
https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/QpEoCwU0Ttg)
some years back, and the w3c agreed -
https://www.w3.org/International/wiki/Locale-based_forms.

This does not appear to have been implemented.

That being the case, what is the current advice for forms?
- just use the native controls and accept their limitations?
or
- create your own controls/widgets to replicate the native behavior, but in
a way that gives you (the developer) control over the locale?
Thanks,
w
