[Dxbase] LoTW ADIF

[Ed Parish K1EP]

When I create an ADIF file, DxBase asks if I am submitting this for LoTW.  If I check YES, it will mark QSOs as LoTW sent.  The question I have is, why does the ADIF file contain a lot of seemingly extra DxBase info if it knows that the file is to just go to LoTW?  I assume that LoTW ignores many of the fields, but it seems to make the file much larger than it really needs to be.  LoTW shouldn't care about fields such as <QSL_VIA:6>, <QSL_RCVD:1>, <DXBQSL_RCVD:1>, <QSL_SENT:1>, <DXBQSL_SENT:1>, <DXBPFX:2>, <DXBMGRN:1>, <DXBAWD:1>, <DXBSEL:1>, or <DXBVAL:1>.  Is it really necessary to include those in the ADIF file if I indicate that I am submitting this file for LoTW?
