DNS is dangerous knowledge to have.

Yes, it's a wonderful, amazing way to solve many problems.

Unfortunately, once you know how it works, you begin to realize how fragile the underpinnings for a lot of other things are.

Worse, once -other- people realize you know it, you get their well-meaning plans to do things that, yes, -can- work, but really oughtn't to see the light of day.

@munin Remember when people were putting a metric shitton of oob non-standard stuff in TXT records?
@maiyannah "Were"?
@munin It's not as bad as it once was.
@maiyannah No; nowadays they just abuse subdomains to try to exfil information using base32-encoded queries.
@munin SPF at least pretends to have it's own proper record now.

@maiyannah @munin "ultimately the working group concluded that significant migration to the SPF RR type in the foreseeable future was very unlikely and that the best solution for resolving this interoperability issue was to drop support for the SPF RR type from SPF version 1."

@terribleplan @munin "Pretend" was the operative word there.
