useLibrary \'org.apache.http.legacy\'
Well, to answer my own question, I've put up project, which will repackage and build HttpClient in bundle with HttpMime, HttpCore and HttpClient-Cache packages into different namespace.
Currently the version provided is 4.3.3 (in sync with ASF HC 4.3.3 version)
https://github.com/smarek/httpclient-android
It's quite customizable, so changing the package/artifact name or version, adjusting the build to your needs and so on should be no problem.
It's also published on Maven Central under identifier cz.msebera.android:httpclient:4.3.3
and all your code imports currently using org.apache.http
should be migrated (for sake of using this library) to cz.msebera.android.httpclient
