Sure but the JIT js disable and limiting of image/video decoders are combined basically all the security from lockdown mode, so disabling it seems pointless.

I do wish it worked more like GrapheneOS, but the other protections outside of web browsing seem to make it worth enabling lockdown mode. Personally, I'm only reading articles on my phone's browser so I'd wonder if I'd be fine with disabled JIT and crippled decoders.
