do you think there are other fields that could be useful there? in theory it is common enough to warrant actual integration, though download statistics suggest that it not used that often anymore.

[johnthagen]

I personally have only used the Base64 fields, but find them very handy. The repo has almost 500 stars and is actively maintained, so that's a plus.

I'm not sure if it warrants official support or not. On the other hand, the other fields might not even require extra schema handling (they may keep everything the same type but just change the representation), so it could end up being easy?

I think your call on integration.

[tfranzel]

if you are interested in doing the integration, I would certainly accept the PR. Personally I lack the time atm. Otherwise, we merge this PR and add integration to the backlog.

Things to consider:

• have a look at the contrib tests to see how contrib packages are tested.
• check if other fields require extensions.

[johnthagen]

@tfranzel I'd say let's merge this PR so that others have the blueprint in the short term and add integration to the backlog. I'm not sure if I have the time currently to work on integration, so I wouldn't want to block others having a solution for now
