Are you confusing the d= value and the DNS node (including selectors and
suchlike) that the public key lives at?
The d= value has been the persistent identifier for the signer since
day one,
while the i= value is a more specific value that the signer can
optionally use.
Given that the RHS of i= is either identical or a subdomain of d= it's
nonsensical
to consider i= more stable than d=, as i= must change if d= does.
