If you do all the steps yourself you have effectively built your own JSON tools (at least the serializer).
If not, you will most likely be affected by the same quirks as any other system that does not simply
wrap the whole text "as is" like the JOSE folks did.
The Go serializer for example escapes '<','>', '&' which is fine JSON-wise but fails in a signature
scheme that doesn't follow the JOSE method. However, there are of course workarounds like running
an "unescaper" pass after serialization. Not exactly rocket science but slightly ugly.
