Actually, QgsServerRequest and QgsServerParameters are high level
classes which are not aware of valid parameters defined in services. For
example, FI_POINT_TOLERANCE is a valid parameter in WMS service, and
defined within the WMS module. But it's totally encapsulated within the
module (a shared library so), and considered as unknown from
QgsServerParameters. The only valid parameters from the
QgsServerParameters point of view are those which are common for all
services (WMS, WFS, and so on) like SERVICE, VERSION, REQUEST, ...
If you want to retrieve the full query from the request without any
filter on valid parameters, you may use request.url(). However, I think
we could probably add a fallback on the `parameter()` method to return
invalid parameters too. I'll do a PR tomorrow and I'll ping you to check
if the behaviour suits you.

Paul
