How do you handle usability issues?
Do you suggest all usability issues are out of scope of JMeter?
I think users are just not aware of the possibility of better life,
thus you do not see requests
"skip rows in CSV file" is a pure usability issue. It has manual yet
painful WA. It has even automatic WA (e.g. some loops in jmx plan).
However, it is just an additional pain for newcomers.
I think "skip rows in CSV file" was asked for before, but mostly in
multi-node setups, where the question was, "how can I read in values,
that are meant to be for this specific node only"
Maybe we could try to solve those two problems in one go. One
possibility would be to add a while loop to the CSVDataSet class where
the values are actually read and use a condition to decide, wheter the
read-in values should be emitted.
For the skip-row case, we could decide on a line-number variable (which
probably would have to be added), in the multi-node setup, we could use
a node identifier.
The condition could even be user submitted for use cases we were not
thinking about yet.
Now that I think of it, we could even use it to "shuffle" the input, by
checking on a random variable. It would probably be not very efficient,
but the third use case, that people ask for often.

if selected, then check if the marker file
is present, and if so skip that many rows.
I do not follow you. Initially you said existing CSV Data Set should
not be extended: "Do you think JMeter core should handle the case --
no".
Now you suggest improving it.
Note that the StringFromFile function has a feature which allows the
use of multiple input files that can be used in sequence
I do not see how it is useful in current context.
When I said "5-10 input files" I meant "5-10 thread groups with each
having its own input file".
