Browser should follow such settings and display value accordingly, but value MUST be sent to server according to 1 set of rules, regardless of anything else (e.g. no thousands separator and full stop as decimal separator). No browser locale, no server locale... one set of rules.

Yes.  What the user enters and sees on screen is a presentational/locale issue mediated by the browser etc.

What an API returns, a form sends, etc., when it is a number in string format, should be fixed.
