Good developer not think WHY to code something, good developer think HOW to do it to complete the goal. If You start thinking "I don't want to do it", "it is too complicated", "it is not worth it", "why on the Earth I should do it", there always will be many workarounds and reasons not to do it not matter what You do.
I was so long time ago, I don't even remember what was the reason to open the issue, tho. Probably because the FreeCAD spreadsheet was not fully compliant with LibreOffice spreadsheet version. After open more advanced version FreeCAD spreadsheet in LibreOffice You had one big mess. So it was better to copy CVS text manually and correct it manually also.
This issue was opened to point out new good feature and make the FreeCAD better. However, If You feel so big pressure and don't want to do it, just remove it and forget about it. I have my workaround and don't cut chipboards daily to feels so big pain in ass without this feature. I was living so long without it, so probably this feature is not worth to ruin someones life
