LGTM to keep going until M115.

I recently discovered that despite me asking for this to run till
M113, the OT is running till M115.
The reason I haven't "renewed" the OT after M113 is that lined-up
partners took a particularly long time to add support, which resulted
in practically no-use for the OTed API (beyond a very small number of
origins

Now I'm interested in renewing the OT for M115, but wondered if the
fact that the OT wasn't effectively used on M113-M114 (nor before,
tbh) could be considered as a gap in the OT, and hence the renewal
won't be considered as extending

beyond the 6 milestone initial limit. Thoughts?

Update: We're bumping the experimentation from M109 to M110 (till
M113), to align with partner timelines (and avoid them
rediscovering bugs fixed in M109).

Specification
Not yet. I want to use the OT's feedback to assess the
solution's viability.
Summary
Exposes the (experimental) soft navigation heuristics
<https://github.com/WICG/soft-navigations#soft-navigations>
to web developers, using both PerformanceObserver and the
performance timeline.

/Other signals/:
WebView application risks
Does this intent deprecate or change behavior of existing
APIs, such that it has potentially high risk for Android
WebView-based applications?
Nope!
Goals for experimentation
I'm interested in gaining insights on the quality of the
heuristic and how it compares to current heuristics employed
by RUM providers or driven by framework- or app-specific
knowledge. I'm also interested in knowing if developers find
the correlation of various performance entries to their soft
navigation ergonomic, and whether the emitted FP/FCP/LCP
entries work well for them to evaluate the performance of
their soft navigations.
Reason this experiment is being extended
N/A
Ongoing technical constraints
None.
Debuggability
Will this feature be supported on all six Blink
platforms (Windows, Mac, Linux, Chrome OS, Android,
and Android WebView)?
No
Is this feature fully tested by web-platform-tests
