[Feature Request] persistent-placeholder for VTextField

Problem to solve

After version 2.4.0, the logic of placeholder behavior changed.

Proposed solution

To save previously implemented features, need to add a parameter persistent-placeholder

We have the same problem. Breaks a application with a few hundred fields and makes a vuetify upgrade impossible. We are using the placeholder for a kind of “fallback value”. If the user does not enter a value, the “fallback value” (placeholder) will be saved. Therefore it is essential that the placeholder is always visible for the user.

I understand that the material design spec does not “allow” these functionality but please give us an attribute to use the old behaviour instead. I know it would be possible to work around and re-implement our needed behaviour, but the reason why we coose to use an ui framework and don’t implement everything from scratch is that we don’t wanted to reinvent the wheel every time and use existing features of a solid framework.

Don’t get me wrong, i appreciate the work the whole vuetify team is doing. If there is something i can help, please let me know.

Introduced in #12635 for #12499 and related to #5753. The changes made are potentially breaking from a design point of view. Reviewing with the team and will update.
