Custom frameworks: ".lcext" or ".lcextd" ?

[trevix]

From the Livecode Builder User Guide I read:

Static libraries and frameworks for iOS must be compiled into a lcext object. Use the build-module-lcext-
ios.sh shell script as an example of how to do so.

But I noticed that almost all the "merge" Monte extensions (on Livecode 10.0.2 RC4) have a folder terminated with ".lcextd", with the addition of a "d".

Is this a change that has been implemented (without telling to anyone)?
