It's hard to know what should be handled as the "normal" case.  When you're
just working with LAS, it seems like PDAL should know what to do, but even
then it's not clear.  As an example to go with your case, if you're using
PDAL to construct some extra dimension that you wanted written out as extra
bytes with each record, you certainly don't want the LAS_Spec/4 VLR
forwarded or the existing extra bytes just tacked on.  We try to make the
common things easy, but sometimes what's common for one person isn't for
others.  Perhaps other times we just didn't anticipate well.
