We can right now configure how many blocks or how heavy ships are allowed on the server. I suggest adding an additional customizability: mass/block limit for blueprints uploaded.
The reason I suggest this is because in the old days of credits for blueprints, you had the hard limit of 2 bil for the ships you could spawn in via blueprints - so like a mass/block limit. This made it so that you could have more expensive ships on the server but they would have had to been made on the server. Something I found good about this is that exceptionally large ships were possible, but they felt more special since they were built on the server and a bit harder to achieve.
Eg: A server owner could decide:
50k mass limit for blueprint ships,
200k global mass limit for ships.
