Custom element v-model : rename type to v-model-type

[Benoit-Vasseur]

What problem does this feature solve?

v-model is now usable on web component :) see #1699 and this commit : 71c3c6e

However I have a suggestion concerning the type attribute on v-model on a custom element.
I think it could be safer to force the "type" and name the prop v-model-type instead of type. type looks to dangerous to me for naming collision. I was also thinking of but I do not think that it respects the design of the modifier, it is more an "adder" in this case.

What do you think : rename type to v-model-type and make it mandatory for custom element with a proper error message ? I can make a PR if you approve the idea :).

What does the proposed API look like?

• <my-custom-elt v-model="model" v-model-type="text" />

I don't really think this is necessary. If you have a custom input element that is expected to work with v-model and have something like type="radio" or type="checkbox" on it, it would be really weird for it to not indicate that "this element behaves like a native radio/checkbox".

Adding yet another built-in directive for this highly unlikely case seems overly cautious to me.
