Ideally we should change the return type of registerPrefix and friends to return a (non-scoped) handle directly rather than a weird pointer type. The non-scoped handle type can be implicitly assigned to the scoped handle type. That would substantially improve usability for new API consumers because they don't have to separately construct the scoped handle passing a Face object, which is ugly. Backward compat for the new return type can be achieved by adding a conversion operator from the handle type to the current pointer type.
I agree and this applies to scheduler::ScopedEventId as well.

Change 4876 patchset 2 attempts note-2 design, but it seems that the implicit conversion operator is ineffective:
../src/mgmt/dispatcher.cpp: In member function ‘void ndn::mgmt::Dispatcher::addTopPrefix(const ndn::Name&, bool, const ndn::security::SigningInfo&)’:
../src/mgmt/dispatcher.cpp:82:39: error: no match for ‘operator=’ (operand types are ‘nonstd::optional_lite::optional<const ndn::RegisteredPrefixId*>’ and ‘ndn::RegisteredPrefixHandle’)

Well, it's failing because the LHS is an optional type... Dispatcher::TopPrefixEntry is using optional<const RegisteredPrefixId*>, which is not something I was expecting since it doesn't make much sense (pointers are intrinsically nullable). I would get rid of the optional and not worry too much about these cases.

https://gerrit.named-data.net/5163 implements the same design as scoped Interest filter.
After this is merged, I plan to do another round of refactoring to deprecate conversions of XHandle to const XId*.

https://gerrit.named-data.net/5198 deprecates Id types in favor of Handle types.
NFD and PSync aren't affected.
https://gerrit.named-data.net/5199 updates ndn-tools.
https://gerrit.named-data.net/5200 updates repo-ng.
I will check ChronoSync, NLSR, and NAC later.
