I think that in the past this value would be enough for most projects as well it was not so usual have a video card that supported it.
I believe we could enable autoUV to use the max value returned by OpenGL, but we need to remember it will make video memory usage to increase a lot. (maybe we need to take care about to not make Wings crash)

You can check that max value in the menu Help->OpenGL Info and looking for Max Texture Size (it's 8192 in the PC I'm now).

[edit]
Just a example: 8192x8192x4(RGBA texture) = 268435456 = 256MB - just for one image.
So, considering the uvmap image has been created as internal not only the video card memory is charged, but the system memory too. Now a days we have a lot of memory and the 64bit version of wings that can make possible load use such textures without any crash.

Thinking about that, maybe we would consider to add 8192x8192 to Create Texture option in autoUV (if available).
