AC formatter in SC validation message?

So I finally gave up on trying to find a workaround that doesn’t imply modifying core files.

I added a “fix” so that the dmxValidator.js would parse the expression:

s.textContent = t.startsWith("'") ? dmx.parse(t) : t
dmx.validate.setBootstrap4Message = function (e, t) {
        if (!e.hasAttribute("data-msg-custom") && (e.getAttribute("name") || e.getAttribute("id"))) {
            var u = e.type.toLowerCase(),
                a = "dmxValidatorError" + (e.form ? e.form.getAttribute("id") : "") + (e.getAttribute("name") || e.getAttribute("id")),
                s = document.getElementById(a);
            s || ((s = document.createElement("div")).id = a, s.className = "invalid-feedback", e.parentElement.appendChild(s)), e.hasAttribute("medium-editor-textarea-id") &&
            (e = document.getElementById(e.getAttribute("medium-editor-textarea-id"))), "hidden" != u && "g-recaptcha-response" != e.name && 
            (t ? (e.classList.remove("is-valid"), e.classList.add("is-invalid")) : (e.classList.remove("is-invalid"), e.classList.add("is-valid"))), s.textContent = dmx.parse(t)
        }
    }

Finally I made sure that the string returned as the validation message was parsable.

In summary:

Can we get validations messages parsed correctly in SC so they can be formatted in AC?

Any string sent from SC is “formattable” in AC as a data binding but SC validation to AC is hardcoded so I can’t apply a formatter.

I would rather avoid having to deviate from standard by patching core files.
