Unsure how common it is, but income protection insurance is a fairly substantial deductible.
Add that in with WFH, work related eduction, tooling, uniform laundry, vehicle costs, professional association or union fees, etc., and you can rack up $1000-$2000 pretty quickly.

I might be wrong on this or might be missing your point, but I thought dnssec was for validating integrity of the request, not to encrypt it like DoT or DoH.
