Delimit UID length

[ettiSurreal]

One neat thing about UIDs is that you can manually rename them and they'll still work. So for example if you open the .import file of an image and change uid="uid://ephy2awyrre5" to uid="uid://cat", then try accessing it with load("uid://cat"), it will just work.

However, one major problem with doing so is that the maximum length of the UID string is hard capped at 13 characters, making one longer than that will cause the UID to silently auto-regenerate.

Is this a limitation of how UIDs are implemented, or is it just an arbitrary limit that can be removed (or extended)?

If you intentionally break these files you're going to run into problems, but all that will happen is that it will regenerate, I don't think we need to handle cases where users manually break things, and we shouldn't assume it's just some specific change, if it's invalid it should just be discarded as invalid

The maximum length isn't hardcoded, nor is it an arbitrary limit, it's simply that UIDs are encodings of 64 bit values which has an upper limit on the length

That makes more sense, I thought the UIDs were simply plain text, which you could freely edit and nothing would break as long as the UID isn't referenced anywhere yet.
