Comment (by aduth):

 Since it's documented to accept a string, I don't know that backwards-
 compatibility would cover the incidental behavior of an invalid usage?

 https://developer.wordpress.org/reference/functions/wp_kses_post/

 Even prior to 5.3.1, the behavior was not strictly-speaking an identity
 function, and could return a different result than what was given:

 {{{
 wp_kses_post( 5 );
 // string(1) "5"
 }}}
