Question about Banglejs 2 HRM capability

I was on the verge of getting an Amazfit Bip S and stumbled upon banglejs yesterday. I am really interested in it, sadly I missed the kickstarter.

One of the updates on the Kickstarter page say

FITNESS

Bangle.js will log steps, movement and heart rate (if enabled) every
10 minutes, 24 hours a day, and can export the data to CSV files.
However initially you won’t get the same ‘insights’ or app integration
that you would from something like a FitBit.

Bangle.js can log GPS,
steps, heart rate into GPX files which can then be imported into apps
like Strava, but again integration won’t be as smooth as on some other
devices.

Bangle.js’s heart rate monitor needs your arm to be still to
get an accurate reading. This will improve with software updates in
the future but right now it’s not suitable for heart rate measurements
while running (for example).

The heart rate monitor is the main thing that sent me on a smart watch search, so I would like to ask:
Does the first point mean the watch can only provide a heart rate reading every 10 minutes? Can an app request it more often to show something more continuous?

Does the final point mean that at some point Bangle.js HRM will be good enough to take measurements while running, or should I stop considering this watch before I get even more excited than I am already?
