Reason for removal of support for Dynamixel models in release 2.2.3

[nilp-dromeda]

I am currently using the newest release 2.2.3 to interact with Dynamixels that we are using. One of the key requirements was to be able to enable Current based position control on the dynamixels. We use a few different versions of dynamixels and most of them were enabled to current based position control, however the dynamixel-workbench-toolbox did not allow for the two models shown below:

• XL330-M288-T
• XC330-T288-T

Upon looking at the source code for release 2.2.3 I realised that a lot of the supported Dynamixel models were removed from dynamixel_workbench.cpp relative to the master branch. I have included a diff file which details the the if condition checks that had a variety of models removed from them (patch file not supported for upload on linux):

Git diff between 2.2.3 and master for dynamixel_workbench.cpp

What is the reason for these motor models not being added from master into release 2.2.3?
