As an addendum to my earlier comment at: https://mm.icann.org/pipermail/comments-reference-lgrs-second-level-24aug20/2020q4/000005.html
Some of the representative examples of confusingly similar looking variants from Devanagari script are:

Variant group 1:
द्र (U+0926 U+094D U+0930)
द्ग (U+0926 U+094D U+0917)
द्न (U+0926 U+094D U+0928)

Variant group 2:
त (U+0924)
त्त (U+0924 U+094D U+0924)

Variant group 3:
श्व (U+0936 U+094D U+0935)
श्र्व (U+0936 U+094D U+0930 U+094D U+0935)

I am sure there are many such examples in Devanagari and other scripts.

The reasoning behind this being, the existing procedure involving of “String Similarity Assessment panel”, a panel whose mandate ( I assume ) is to evaluate every incoming label for the Root Zone vis-à-vis all the existing labels in the root zone and take a judgement call whether incoming label is in any way confusingly similar looking with any of the existing label in the root zone.

However, not all the environmental conditions present at the Root Zone are as it is applicable to the second and higher level domains. The case in point for this comment being the absence of any formal and known universal structure at the second level similar to string similarity assessment panel.

They all may need to be made part of a blocking variant set.
