No. I was thinking more on the line with making the limit more flexible like let's say you have 30 nobles in a realm with 10. Then you can expand to 15 without any penalty while if you have a realm with 10 nobles, you can't expand beyond 5 without suffering penalties. So limit would continue to go higher the more nobles you have. It will limit your realm as you lose nobles overtime.
Penalties could be different things too. If you want to avoid punishing people directly for losing density, you can simply make it impossible to expand or regions without lords a lot less efficient in terms of resource production. Or more likely to fall to takeovers.
