[Documentation] Definition of SUBSCRIPTION_MAX_INTERVAL_PUBLISHER_LIMIT vs ICD

[Apollon77]

Documentation issues

The specificiation tells:

SUBSCRIPTION_MAX_INTERVAL_PUBLISHER_LIMIT defines the upper limit for the publisher-selected maximum interval for any subscription.
◦ If the publisher is an ICD, this SHALL be set to the Idle Mode Interval.
◦ If not, this SHALL be set to 60 minutes.

In my understand this means:

• an ICD device (aka mostly Battery powered ones with limited power) define an "Idle Mode Interval". An Eve Door&Window as example - ok this one does not have ICD right now - but uses SII=10s which I consider comparable. This means that formally this device "SHALL" have a maximum subscription interval of 10s ...
• any non ICD device (mostly also non-battery powered with many power resources) should set max to 60minutes nd may decide for shorter intervals

So when a controller requests 120s from Eve Door&Window then the device formally need to respond with 10s as max interval (unless the controller wants a higher max timeframe) which is the worst case for battery inn my eyes. SO in this case it is completely controller bound how long the battery holds.
Should not - especially for battery devices - the device have some more options to "protect" the battery life best possibly?

Is this really wanted that way?

Or is the Idle Interval in ICD not "the same" as SII?
