Is an edging strip necessary?

A lot of better grade Porcelain are a solid Colour all the way through..
I have had customers that prefer to see the natural edge of the Tile as apposed to trim.. ( Which I prefer the look of)..As trim can sometimes be too eye catching and evident.

My guy mitred all tiles in kitchen and bathroom and i love how it looks. I feel it looks and feels more minimalist and polished like this.
