Primary-name adoption by length

Of currently-active .eth SLDs in each length bucket, what fraction are actually used rather than just held?

Counts names where the owner has set a primary name (reverse record) on any namespace pointing back to that domain.

What this tells you:

High adoption implies real users who care about display identity.
Low adoption implies names held without active use in mind e.g. speculative inventory.
For the pricing debate: if 3-character survivors have notably higher primary-name adoption than long-name survivors, the price filtered for utility users.

Length	Active	With primary	Adoption
3 chars	2,850	712	24.98%
4 chars	9,574	2,456	25.65%
5 chars	98,866	34,387	34.78%
6–9 chars	390,470	139,307	35.68%
10+ chars	307,202	91,469	29.77%

Methodology

Active .eth SLDs only (depth=2, parent='eth', expiry_timestamp >= now).
Adoption = owner has a primary name on ANY reverse namespace (addr.reverse, default.reverse, or any ENSIP-19 chain-specific registrar) that resolves exactly to this domain's full_name.
Doesn't require forward-resolution match against the addr record - that would be a stricter definition; here we just check the reverse side.
