I wrote a simple, locally running Webapp some time ago, that targets the Lemmy Import-/Export-API and supports transferring only specific userdata between accounts, as demonstrated in this corresponding Wiki Entry.
The import functionality in Lemmy is additive in nature, meaning anything you import gets added on top of existing settings instead of replacing it.
Does the same thing as these manual instructions for this usecase, may be helpful to some.
15-20 years ago, I'd have agreed with you. But apart from a select few news sites and exceedingly rare static sites, what percentage of websites most users use day to day actually function even minimally without JavaScript?
I'm convinced that in practice, most users would be conditioned to whitelist pretty much every site they visit due to all the breakage. Still a privacy and security improvement, but a massive one? I'm not sure.
Very happy to be convinced otherwise.
