There have been recentish statements from your colleagues that could be interpreted otherwise:
"Datatypes [...] are mostly broken by design and Reggae is so much easier and flexible in any way." http://morph.zone/modules/newbb_plus/viewtopic.php?forum=3&topic_id=11382&start=86
"basically only some shell commands and libraries/datatypes are based on AROS. Many of those are only present to be backward compatible even that there is a replacement already. Since compatiblity with 68K is no longer an issue in the future those likely will be dropped. datatypes [...] for example are basically already quite obsolete. [...] Reggae is a nice replacement for datatypes." http://morph.zone/modules/newbb_plus/viewtopic.php?forum=3&topic_id=11372&start=54
"datatypes suck, imo ;) There's a reason for Reggae." http://morph.zone/modules/newbb_plus/viewtopic.php?forum=3&topic_id=11301&start=30
