Is anyone still using PPP at all?

After talking to colleagues about how easy it is to contribute to the Linux Kernel simply by reporting a bug, I was actually wondering why I was the first and apparently the only one to hit this bug.
So there are two possible reasons:

• nobody is testing -rc kernels
• nobody is using PPP anymore

To be honest, I'm also only using PPP for some obscure VPN, but I would have expected it to be in wider usage due to UMTS/3G cards and such. So is nobody testing -rc kernels? This would indeed be bad...
