Since you mention them ... I probably miss something obvious but from
looking at the documentation of if-let

    if-let is a Lisp macro in ‘subr-x.el’.

    (if-let BINDINGS THEN &rest ELSE)

    Process BINDINGS and if all values are non-nil eval THEN, else ELSE.
    Argument BINDINGS is a list of tuples whose car is a symbol to be
    bound and (optionally) used in THEN, and its cadr is a sexp to be
    evalled to set symbol’s value.  In the special case you only want
    to bind a single value, BINDINGS can just be a plain tuple.

and of if-when

    when-let is a Lisp macro in ‘subr-x.el’.

    (when-let BINDINGS &rest BODY)

    Process BINDINGS and if all values are non-nil eval BODY.
    Argument BINDINGS is a list of tuples whose car is a symbol to be
    bound and (optionally) used in BODY, and its cadr is a sexp to be
    evalled to set symbol’s value.  In the special case you only want
    to bind a single value, BINDINGS can just be a plain tuple.

I don't get, why there is a need for if-when?
