I agree that these letters may be confused by some internet users.
Nevertheless, our work is not the only check to avoid TLDs from being
registered that would be confused. There is always the second manual review.

Ok, they say we MAY do this, but we don't have to. Therefore I'd say
that we first concentrate on the work we have to do. Let's make sure we
can finish that in time. If then there is some time left, great, we can
take a look at the capital letters and whether there will be in-script
and out-of-script variants. The additional work is not to be
underestimated. We have to compare all capital letters with all
lower-case ones, as well as all capital letters with each other.

I am not generally against doing this, just not at this time.
