One reason to stick to a restricted naming scheme for tables is that table names cannot be parametrized. This means you need to implement escaping manually in tools/scripts where table names are not hardcoded. Snake casing creates word boundaries that do not rely on casing and thus do not need to be quoted, there for your manual escaping/sanitization is greatly simplified (lowercase ascii characters, numbers and underscore). I’ve found this reduces the number of footguns by one in databases maintained by a team with varying degrees of familiarity with RDBMS.
