David Waite:

The current [SIOPv2 spec states](https://bitbucket.org/dwaite40/connect/annotate/master/openid-connect-self-issued-v2/openid-connect-self-issued-v2-1_0.md?at=master#openid-connect-self-issued-v2-1_0.md-343):

`The entire URL MUST NOT exceed 2048 ASCII characters.`

While URL continue to have limits, these have grown substantially larger in modern browsers and operating systems.

I will do experimentation of the size limits across various browsers and operating systems, but I believe the min max is now over 64kb excluding IE 11. At the OS level, this may be even larger \(on the order of MB\).
