Yes, the one MAJOR drawback in using CSV as the file format for Easy Populate, is the enormous potential for errors when content contains commas or quote marks.

EP version 1.2.5.4 used a TAB-DELIMITED system, which is far, far safer and more reliable than CSV - because TABS are not used anywhere in the formatting of the content.

I do not use EP 4 because it is a huge mission to clean up the content, and I have had too many disasters where a single comma (missed in the clean-up) has caused major damage to the site's product data and configuration.

If EP4 created TAB-DELIMITED files, it would be an excellent module.
