Main issue:More extensible object and collection converters

One common aspect is being able to change serialization options on a per-type basis, but without per-type converters or custom attributes. This would be implemented as a virtual method that can be overridden to expose or create the "metadata" classes including JsonClassInfo and JsonPropertyInfo.

This could be achieved by making JsonSerializerOptions non-sealed and adding virtual methods like:

protected JsonClassInfo GetJsonClassInfo(Type type);

However, with the planned work on code-gen and the JsonContext class similar behavior is already there in the form of:

Update (January 11th, 2022)

This document is a point-in-time status update for reflection work that was being prototyped in V6 but didn't make it in mainly due to lack of support for __makeref(ref struct) and the ability to have a collection of TypeReferences.

Please refer to the User Story for the current status of this feature.
