The map is referenced within the BytecodeDialectWriter, so this is mostly convenience - the alternative is to pass the writer configs to the BytecodeDialectWriter itself. Reading multiple versions is really needed for the callback-mechanism (where you could use version X to conditionally emit encodings for dialect Y). For the other cases you should not need to query registered versions other than `self`.
