I do not find vector tiles and client-side rendering suitable for 
archival purposes. I am confident that in 5-10 years there will be 
software that can display xyz tiles on current computers, and in 30-50 
years PNG tiles will still be readable. I do not expect the same to be 
true for any of the client-side rendering libraries working with an old 
style.

The script I have at https://github.com/pnorman/lz-prerender might be 
useful for you. I'm considering making pg_dump files available, which 
could be useful if you're using something that takes the standard 
osm-carto schema.
