Hello. In the process of updating some outdated plugins from 1.X.X to 1.14, there were a lot of occurrences where the old material name is not in the Material enum values anymore, but instead an unmotivating, deprecated legacy one. Many Materials had a replacement, such as the DIODE being a REPEATER, etc. But on the other hand, many were not, such as PISTON_MOVING_PIECE having no modern counterpart. So, I got a few questions I wish could be clarified: 1- Are legacy enums subject to removal in future versions, for instance, 1.15? 2- Are ALL legacy enums supposed to have a safer/modern counterpart? 3- Those who do not have a counterpart, are developers expected to use the legacy one? Because if so, this leads back up to the first question. Thanks in advance.
