Dolphin is actually pretty much aligned with Konqueror.
Konqueror can open up anything using KDE's KParts.
Applications and libraries provide different KParts and Konqueror is just a shell that can open them all.
Dolphin is Konqueror's KPart provider for file browsing.
So basically Konqueror's file browsing capability is provided by Dolphin.
heres a more recent groff implementation of it the macros: https://linux.die.net/man/7/groff_ms prob not what you're looking for, you prob want to get ahold of the orig nroff/troff files
the implication for me at least is a lot, and yeah a lot more has come to exist since so shrug still nothing like using a troff/nroff from 1984 I spose
There really should be some way to accomplish this with IPFS, which imho is better suited for it given that it's multi-purpose, cloudflare has a gateway, and you can register EthDNS names for IPFS hosted content.
I think it might be a good idea to use something like IPFS to distribute keys. Now that cloudflare seems to want to support it officially, the only exception to why they might not are the same kind of lawsuits that brought down the pirate bay but cloudflare has opted to offer content blacklisting/cache refuse in their terms of service so I'm not sure how that's going to work out, but so far since 2018 nothing seems to have changed. I'm not really sure what their takeaway is though, it must provide them some benefit otherwise it's just a waste of their money to provide a gateway service. I'm not sure how well it's going to scale once people start building on it and actually use it more.
I want to add to that the ethereum name service, https://www.increaseo.com/eth-domains-ipfs/ could also potentially play a role in a means to efficiently and reliably distribute public keys in conjunction with IPFS? Seems worth considering at least.
I've been wanting to get it to execute the bonjour conformance test on linux so I can do CI of Avahi against it. I didn't have any luck last time might be worth a look again.
