Context: https://forum.uavcan.org/t/proposed-change-to-variable-length-arrays/740

Affected sections of the Specification:

  • 3.4.4.4 Type polymorphism and equivalency
  • 3.5.3.1 Offset attribute
  • 3.7.4.2 Variable-length array type
  • 3.7.5.1 Tagged unions

Changes: the bit length of the implicit field shall be rounded up to the smallest of 8, 16, 32, 64.

A new directive reversing this behavior may be introduced in v1.x (x>0).
