Mostly these are deprecations from the Spigot team which I believe
shouldn't be deprecated. For example, players refer to each other by
name, not UUID - so there will always be a need for player lookup by
name. Also the block IDs are a well-documented standard that everyone
understands, even if they're not very human-friendly. Plugins use those
IDs and data values to specify block types for example in config files.
As for the rest of the ignores, I either decided the warnings are just
noise based on the situation, or that I'm comfortable with the risks.
Possibly for the first time in 5 years of dev work on this plugin, I
just compiled without any warnings. :)
Should effectively protect basements and other underground bits of
surface-level structures from the moment of creation, provided the
underground bits connect to the above ground bits via player block types
(those which don't abundantly generate in the world).
