Speaking as an owner of a well-behaved mechanical clock:
Clock rate performance over time can be done based on time interval measurements anchored to a solid frequency standard. No 1pps needed per se.
Bring a clock to time is simplified with a timescale-accurate 1pps source.

I have spent a lot of time, effort, and money on developing my GPSDO without a whole of thought to the user base. It was just a quest for the best result I could obtain with a particular technology. The frequency standard users was a no brainer. Everyone who wants a frequency standard eventually understands they need to get a GPSDO, or an Rb, or a Cs. And that's all I thought I had: a good frequency standard. And then Tom prodded me a bit and showed me the shortcomings of what I was doing, and I did something about it. So, if an NTP user can get his time fix directly from a noisy receiver, who actually needs a time-accurate, low jitter 1PPS pulse?
