oox service mess

Before 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=8ada1cd2846e5e60ad63250c68ddea3a9356546f> 
"move excel related oox bits to sc," the following six UNO service 
implementations were listed in oox/util/oox.component, included in 
oox_component_getFactory (source/core/services.cxx), and implemented in 
the oox library:

> oox::ole::WordVbaProjectFilter, "com.sun.star.comp.oox.WordVbaProjectFilter"
> oox::xls::BiffDetector, "com.sun.star.comp.oox.xls.BiffDetector"
> oox::xls::ExcelFilter, "com.sun.star.comp.oox.xls.ExcelFilter"
> oox::xls::ExcelBiffFilter, "com.sun.star.comp.oox.xls.ExcelBiffFilter"
> oox::xls::ExcelVbaProjectFilter, "com.sun.star.comp.oox.xls.ExcelVbaProjectFilter"
> oox::xls::OOXMLFormulaParser, "com.sun.star.comp.oox.xls.FormulaParser"

However, with that commit (making its debut in LO 3.6.0, it appears):

> oox::xls::ExcelFilter, "com.sun.star.comp.oox.xls.ExcelFilter"

is now correctly listed in sc/util/scfilt.component, included in 
scfilt_component_getFactory (sc/source/filter/excel/xestream.cxx), and 
its implementation moved to the scfilt library.

> oox::xls::OOXMLFormulaParser, "com.sun.star.comp.oox.xls.FormulaParser"

is erroneously listed in sc/util/scfilt.component but not included in 
scfilt_component_getFactory (sc/source/filter/excel/xestream.cxx); its 
implementation got initially moved to the scfilt library, but has since 
been removed as it was unreferenced.

> oox::xls::BiffDetector, "com.sun.star.comp.oox.xls.BiffDetector"
> oox::xls::ExcelBiffFilter, "com.sun.star.comp.oox.xls.ExcelBiffFilter"
> oox::xls::ExcelVbaProjectFilter, "com.sun.star.comp.oox.xls.ExcelVbaProjectFilter"

are all suspiciously neither listed in sc/util/scfilt.component nor 
included in scfilt_component_getFactory 
(sc/source/filter/excel/xestream.cxx), but their implementations were 
initially moved to the scfilt library and have since been removed as 
they were unreferenced.

> oox::ole::WordVbaProjectFilter, "com.sun.star.comp.oox.WordVbaProjectFilter"

appears to have been removed for good, neither listed in 
sc/util/scfilt.component, nor included in scfilt_component_getFactory 
(sc/source/filter/excel/xestream.cxx), nor has its implementation been 
moved to the scfilt library.

Can anybody shed light on which parts of this were intentional and which 
were accidental damage?
