In the 10.0.0 release notes it is said that the pre 10.0.0 functionality can be achieved with:

Joi.boolean().truthy('true', 'yes', 1, '1').falsy('false', 'no', 0, '0')

This is not quite the same as the old schema as the new implementation with set doesn't use the insensitive flag when checking for set membership

Joi.boolean().truthy('true', 'True', 'TRUE', 'yes', 'Yes', 'YES', 1, '1').falsy('false', 'False', 'FALSE', 'no', 'No', 'NO', 0, '0')

but still wouldn't cover bizarre capitalization permutations (TRUe) like the previous behavior.

Would you (Joi team) be open to a PR that makes truthy and falsy values entered be case insensitive? I'm willing to do it but want to make sure it fits into the project's roadmap.
