Will ｟ survive being pasted?

Normalisation. No. Anything that applies NFKC — search indexes, usernames, domain names, programming identifiers — rewrites ｟ as ⦅. Safe for display, not for storage.
Legacy encodings. ｟ is Unicode-only — it has no Latin-1 equivalent, so a system stuck on an 8-bit encoding cannot represent it.
Size. 3 bytes in UTF-8. Character-limited fields — SMS, bios, some form validators — usually count bytes, not characters.

Other parenthesis characters

Unicode names 13 characters ending in “parenthesis”. They differ by direction, weight or decoration rather than by meaning.
