More can't get warning from REPL

reproduction steps

using Scala 2.13.3,

➜  scala git:(2.13.x) scala -Wconf:any:e -e "val 1 = 2"
/tmp/scalacmd4109052077779337000.scala:1: error: Pattern definition introduces Unit-valued member of $anon; consider wrapping it in `locally { ... }`.
val 1 = 2
    ^
➜  scala git:(2.13.x) scala -Wconf:cat=other-match-analysis:e -e "val 1 = 2"
/tmp/scalacmd6910894456112894911.scala:1: error: Pattern definition introduces Unit-valued member of $anon; consider wrapping it in `locally { ... }`.
val 1 = 2
    ^
➜  scala git:(2.13.x) scala -Wconf:cat=other-match-analysis:e
Welcome to Scala 2.13.3 (OpenJDK 64-Bit Server VM, Java 15).
Type in expressions for evaluation. Or try :help.

scala> val 1 = 2
scala.MatchError: 2 (of class java.lang.Integer)
  ... 32 elided

scala>

problem

I can't get it to show me the warning, and not try to evaluate.

Also, just to verify, though I don't remember when it does anything,

scala> :warnings
Can't find any cached warnings.

The author intended to exclude the warning in REPL.

My objection is that the REPL is supposed to tell you exactly what scalac will tell you, with no IDE or linter or add-ons interfering with the signal. (That is why snippet templating is perilous. Also why REPL "history import" causing spurious warnings is more than annoying. This is apart from whether REPL template demonstrates standalone performance characteristics.)

The expected result with the REPL check removed:

➜  snips skala -Wconf:any:e
Welcome to Scala 2.13.6-20210312-021334-93ec1f0 (OpenJDK 64-Bit Server VM, Java 15).
Type in expressions for evaluation. Or try :help.

scala> val 1 = 2
           ^
       error: Pattern definition introduces Unit-valued member of $iw; consider wrapping it in `locally { ... }`.

scala>

The idea of excluding the warning is that nobody cares about this in REPL:

scala> val 1 = 2
           ^
       warning: Pattern definition introduces Unit-valued member of $iw; consider wrapping it in `locally { ... }`.
scala.MatchError: 2 (of class java.lang.Integer)
  ... 34 elided

So one may distinguish the REPL function, which is also pedagogical, from the shell function exemplified by amm.
