[fpc-pascal] setting a custom driver in TReader

I'm wondering how to set a custom driver object for TReader instances.
Both in TReader and TWriter the Driver property is read-only, but in
TWriter I can at least use the alternative constructor which takes a
TAbstractObjectWriter. TReader only has the constructor which takes a
TStream and a buffer size Integer. Why is that?
Actually, this slightly ugly snippet from LResources/CreateLRSReader
shows that I'm not the only one trying to do this (where Result is a
// hack to set a write protected variable.
// DestroyDriver:=true; TReader will free it
Any hints why this is implemented as it is, and whether there are
cleaner ways of using custom drivers would be highly appreciated.
