As you're aware, the tokenizer doesn't actually "use" incremental mode -
rather, it is intended for use along with incremental mode.  But we can
always experiment with other combinations.

Yes, unfortunately you can't use --rules on top of --incremental.  But
you can use --rules-stack!  Yes, without any other rules "below" this
stack - that's not required by that option.  Yes, this is weird.

You can also use an external mode filter or/and mask mode with ?w on top
of incremental.

Thank you for making this additional guess as to what Pentester LAB
might have meant.

Perhaps Pentester LAB doesn't actually need any of this complicated
stuff - neither incremental+rules, nor tokenizer - and instead needs
PRINCE mode, which is supported along with rules.
