Regarding the user of case-differentiation in identifiers, I would suggest
that it be used in an entirely consistent manner, rather than being used
ad hoc simply to differentiate variant commands.  For my own purposes,
I use case to differentiate between defining and applied occurrences:
for example, \Section {} _defines_ the section (i.e. it takes the name
of a section as parameter and internally defines a concealed identifier
through which the section can be referenced); \section {}, on the other
hand, is the _applied_ occurrence -- it, too, takes the name as parameter,
but in this case looks up the equivalent internal identifier and returns
the number of the corresponding section.  Thus my documents typically
resemble:

\Section {Introduction}
.
In \section {Introduction}, we met the concepts of ...

There may well be other, pehaps better, uses of case differentiation,
but I strongly suggest that it be used _consistently_.
