I have a Lyman GPR the rifle has a hooked breach and an easily replaceable flash hole liner. Therefore I routinely remove the liner during a cleaning session.
The idea that any rifle manufacturer can and does cut the flash hole threads and liner threads so precisely that their fit can’t admit any fouling driven into the gap between the threads by chamber pressure on the threads is ridiculous.
That’s why anti seize compound or heavy grease is liberally wiped into these threads during their assembly, to prevent migration of fouling and water around these threads.
But to expect the anti seize or grease to prevent fouling entrance into the threads after multiple detergent laced cleaning sessions is ridiculous.
So in short vent liner should be removed occasionally to inspect and clean the threads and what lies beyond and to renew the anti size or grease, as it won’t last for years without some attention.
