This shows that the size increase is neglectable and not worth the increased hassle when it comes to debuggin inside wasm.

Isn't the runtime cost of logging large data instead of "stripped" also worth investigating?
This could affect how many transactions a collator can pack in the 2s of execution and therefore throughput. Or are we safe to assume that runtime logging is not enabled in production and has no effect?
