Should I remove incomplete bisulfite conversion in the BSSeeker2 call step?

Question

[colin.kern]

I have a question about these two arguments for the BSSeeker2 methylation calling step:

-x, --rm-SX           Removed reads with tag 'XS:i:1', which would be
                      considered as not fully converted by bisulfite
                      treatment [Default: False]
--rm-CCGG             Removed sites located in CCGG, avoiding the bias
                      introduced by artificial DNA methylation status
                      'XS:i:1', which would be considered as not fully
                      converted by bisulfite treatment [Default: False]

Both of these seem to be removing false positives from the results, which seem like a generally good thing to do, but their default value is "False". Usually the defaults for a program are calibrated to the most general use case, but I'm not sure if that's the case here. Is it standard practice to use these arguments? Why would I want to not use these?

I have RRBS data, not WGBS, if that makes any difference.
