drop ignoring @internal

[TomasVotruba]

This annotation clearly states that method is used for internal purpose - usually public method, that should be private -, so it should not be displayed and turning it off doesn't make sense. It would be like using reflection to make public method private.

Show only in source code.

Small comment regarding this on @internal:

The @internal tag can be used as counterpart of the @api tag, indicating that the associated Structural Elements are used purely for the internal workings of this piece of software.

An additional use of @internal is to add internal comments or additional description text inline to the Long Description. This may be done, for example, to withhold certain business-critical or confusing information when generating documentation from the source code of this piece of software.

While from my understanding we do not support @api tag, perhaps this had use-cases from the previous users and we should consider bringing it back.

Please try to keep features frozen until we're ready with 4-year old task of replacing Reflection.

We need to focus our attention there. Having that done, we can easily ad new features, don't worry.
