There are 3 types of validations in general.
There are only 3 types of inputs.
Explaining them need lots of word as well as for other
fundamentals/principles related to this.

You are referring to "Business Logic Validation" which needs feedback to
users in case
they send incorrect values.
"App Level Input Validation" does not require feedback other than "You sent
really bad
request. This has been reported to admins." Therefore, App Level Input
Validation can
validate ALL inputs at once and there is no good reason not to do this.
Btw, you can use the validator for a single value validation as well. It
also able to
disable Exception so that one can use it for "Business Logic Validations"
as well.
