Bug#1105984: kotlin package and optional dependencies

[Federico Kircheis]

Package: kotlin
Version: 1.3.31+ds1-3
Severity: normal
X-Debbugs-Cc: federico at kircheis.it

Dear Maintainer,


I'm using the kotlin package since I wanted to use the kotlinc compiler, 
and noticed that it lists following packages as dependencies

  * ant
  * libmaven-compiler-plugin-java
  * libmaven-plugin-tools-java
  * libmaven3-core-java
I'm not using ant or maven, so this install (through transitive 
dependencies) over 300 MB of unnecessary data:

----
Summary:
   Upgrading: 0, Installing: 76, Removing: 0, Not Upgrading: 959
   Download size: 69.8 MB
   Space needed: 324 MB
----


If I force the installation without those packages, I get following summary:

----
Summary:
   Upgrading: 0, Installing: 3, Removing: 0, Not Upgrading: 959
   Download size: 0 B / 6,380 B
   Space needed: 27.6 kB
----


Since the kotlin compiler does not depend on 
libmaven-compiler-plugin-java libmaven-plugin-tools-java 
libmaven3-core-java ant, would it make sense to move those dependencies 
to recommended, or remove them altogether?

The complete list of installed transitive dependencies is
