The limitation you may be thinking of is on the length of link fields
(eg. INP/OUT). In the 3.16 series these can be arbitrarily long.
The length of a DBF_STRING field remains unchanged. The usual
workaround is to use a waveformRecord with FTVL=CHAR. This isn't new to
3.16 though.

Are you able to test with the latest 3.16.x code from VCS? I've been
testing this with asyn/areadetector for some time now and haven't seen
this behavior.
Can you verify that the final .dbd file contains the line:
