Memo backend can handle both BCH and Namecoin transaction (very similar networks). If Namecioin Identity is found for a particular Memo public key, the UI displays and highlights it.
Can be positioned as somewhat advanced feature for those who want unique names on Memo.
Namecoin registrations are very cheep, 0.01nmc or ~6 cents at current prices. FYI, Namecoin is the first ever fork of Bitcoin, and Satoshi participated in it’s discussions.

Also, Memo can have special “associate domain name” action, and if this domain has “memo”:”%account address%” in its TXT DNS record, the UI displays domain name in profile
Inspired by OpenAlias.org
For example, Roger Ver puts memo:bitcoincash:qzenpwe2cdvkrvnxcnp0lj2n492xu8z8uca0syfr88 into TXT DNS record of rogerver.com domain name
If Roger has performed “associate domain name” action and put rogerver.com in opreturn, memo backend fetches dns record, verifies it, and if ok UI dispolays green mark next to name
