Sort of a String#replace for working with Components

I’m looking for a way to take a config value like %displayname%: %message% and replace %displayname% and %message% with components (and somehow probably also parse & color codes at the same time (ex. %displayname%&r: %message%))

Example: (simplified for demonstration purposes, in the real world the replaced components could have click & hover events and wouldn’t just be a simple text component with just content)

Component comp = TextComponent.of("%displayname%: %message%")
    .replace("%displayname", TextComponent.of("Steve"))
    .replace("%message%", TextComponent.of("Hello World!"));

https://github.com/KyoriPowered/text/blob/master/api/src/test/java/net/kyori/text/TranslatableComponentTest.java is as about as good of an example I can find for this. (thanks for the pointer, @wizjany)

var renderer = FriendlyComponentRenderer.from((locale, key) ->
        new MessageFormat("{0} and {1} are cats."));
renderer.render(
    TranslatableComponent
        ...
        .args(
            TextComponent.of("kashike"),
            TextComponent.of("lucko")
        )
        ...
);

I’m not really a fan of using the argument index to do the substitution though… I can already see users messing it all up seeing as these messages will be user-configured. Is there anything comparable to this but with named arguments or will this need to be done by the implementing library? I feel like this would be a useful addition if there isn’t something already.

var renderer = FriendlyComponentRenderer.from((locale, key) ->
        new MessageFormat("{thing1} and {thing2} are cats."));
renderer.render(
    TranslatableComponent
        ...
        .args(
            "thing1", TextComponent.of("kashike"),
            "thing2", TextComponent.of("lucko")
        )
        ...
);

Use a translatable component? then you can use the friendly renderer and provider a translation function that replaces placeholders with values.
