Performance profile API in Safari 10.0 iOS dont have methods 'mark', 'measure' and 'getEntriesByName'

[dutscher]

Stencil version:

 @stencil/core@1.7.0

I'm submitting a:
[x] bug report
[ ] feature request
[ ] support request

Current behavior:
Your Browser support says Safari 10.1+ https://stenciljs.com/docs/browser-support.
When we look onto the Mac Safari 10 https://en.wikipedia.org/wiki/Safari_version_history#Safari_10, we can see in 10.1 is new "New web technology additions and improvements".
BUT!
We talk about iOS. https://en.wikipedia.org/wiki/Safari_version_history#Safari_10_2
It is a 10.0 minor.

I found, that in 1.7.0 the profiling was add or optimized:

runtime: add performance profiling (f5817a0)

The API on iOS 10.0 for profiling exists, but dont has the methods mark, measure and getEntriesByName.

A workarround that all webcomponents are hydrating is to use stencil build --no-profile, which is nowhere documented.

Why is BUILD.profile default true and not false?
Is there a documentation?

Expected behavior:
iOS 10 works out of the box as the Browser Support says
