MicrosoftBleddyn_James Excel.uservoice.com is still the correct forum for product suggestions. We do monitor the suggestions and the voting there as important input to influence our plans. The site doesn't highlight completed suggestions when you're looking at the list, so we prepared this post to show that we do take the input we receive seriously - https://techcommunity.microsoft.com/t5/resources-and-community/how-your-ideas-on-excel-uservoice-com-help-improve-excel/m-p/1587487.
Again, there are many factors that have to be considered and numerous reasons for prioritizing one suggestion over another. With regard to the suggestion you mentioned, applying conditional formatting to named ranges, complexity and risk is an important consideration. Since named ranges can be dynamic (changing when the workbook recalculates), and conditional formatting also happens during recalculation, it's quite complex to make this work right and avoid introducing performance issues.
