The TypeDecorator.cache_ok class-level flag indicates if this custom
TypeDecorator is safe to be used as part of a cache key. This flag defaults to
None which will initially generate a warning when the SQL compiler attempts to
generate a cache key for a statement that uses this type. If the TypeDecorator
is not guaranteed to produce the same bind/result behavior and SQL generation
every time, this flag should be set to False; otherwise if the class produces
the same behavior each time, it may be set to True. See TypeDecorator.cache_ok
for further notes on how this works.

As I don't know if those can be safely cached, just disable the warning.
