Which is exactly why I think registries should be penalising registrars the
are plainly not validating IDNs they submit in <domain:check> commands rather
than requiring language tags be provided in <domain:check> commands.

Essentially, I'd prefer misbehaving registrars were penalised rather than
having well-behaved registrars such as ourselves[1]. Without the language tag,
we're able to batch multiple checks from multiple customers into a single
request. This makes our store more responsive. Requiring a language tag be
provided means this ability to batch checks is reduced because we'll have to
group domains in batches based upon the language code.

I can't emphasise how important it is for a registrar that domain availability
checks be quick. Anything that compromises response time in this area means
potential loss of sales.
