Performance problem in `Dry::Validation::Rule#each`

A certain combination of schema validations, rules and data lead to performance problems.

rule(:users).each do
  # ...

The culprit seems to be Dry::Schema::Result#message_set.
That is, it seems that building the MessageSet is expensive.
In combination with a big data set to validate, this method is called very often via Dry::Validation::Rule#each, hence leading to mentioned performance problems.

Is there an easy way to memoize the result of Dry::Schema::Result#message_set for the case where options = EMPTY_HASH is passed as argument? If yes, this might be enough to solve this problem.
