I thought about it and just realized nowadays CPU very quickly decrypt small text in the browser, at least for NaCl and many others, thus, apart recommending an algorithm like NaCl (as we've thought, it was the best), we should also recommend apps to auto trying decrypt VSYS TRX's messages with NaCl in order to check a potential "hidden message", like a kind of a "smart decrypt" which knows it can be encrypted with the receiver public key with NaCl or McEliece (I saw it was very unlikely to be recommended to use McEliece without another synchronous encryption algorithm, more than that without being sure of that, it seems that the vsys keypair aren't compatible with McEeliece) :/

We can: Recommend smart auto decrypt systems :)
We can: Recommend officially NaCl while not recommending McEleice among other...

The most open, free, and acceptable solution IMHO.
