Are software developers really a small market?

There is probably low priority/ignored because most developers can easily do this on their own, so it's not really worth the hassle.

Some googling shows ~20 million software developers around the world. Some googling shows roughly 2 billion households globally and 50% of them have a PC in their household. So let’s say 1 billion PC users.

20 million / 1 billion = 2%

So yes, it seems like a small market relatively.

Remember Steve Ballmer?

Developers are incredibly important for an ecosystem and having them a bit more optimistic about a platform can be quite beneficial (for a very low price, even).

They were a significant portion of getting OSX to the masses, but became less and less relevant to Apple over time.

Just an FYI, 1Password can now manage ssh keys that you can authenticate with TouchID

Still they bother to compile ssh, git, they even got some custom OpenSSL binary. They definitely have some resources allocated for “non-profit” development tools.

Maybe.. but it would also make it way easier for 'normal people' to use SSH keys / signing.

Seems like a natural thing to have in keychain.
