An element for user input of a real number in a format that uses a suitable 
decimal separator is hardly a "specific need". By "suitable" I mean that the 
separator corresponds to the user's preferences _or_ the conventions of the 
(main) language of the page - it is not clear which one should be used, but 
using either a full stop in all cases (against the rules of most languages 
of the world) or an unpredictable separator is hardly suitable.

This is not about "more features". This is about the implementations, and 
implementability, of the feature <input type="number">.

Is rather about "less features". Maybe <input type="number"> should be 
restricted to integer input only, on the ground that useful features with 
fairly straightforward implementability should be added, without waiting for 
clarification of issues related possible extended formats of the features.

It might even be a good idea to add an element for real number input later 
as, say, <input type="real"> rather than allowing <input type="number"> to 
accept real numbers. This would allow e.g. an implementation to provide a 
virtual keyboard for <input type="number"> with only digits, "+" sign, and 
"-" sign, making it clearer that only whole numbers are expected.
