Yes, it is. https://developer.apple.com/library/mac/documentation/UserEx... says "Table A-2 lists the system-reserved and commonly used keyboard shortcuts mentioned in the rest of this document."

Table A-2: contains ../art/ks_option_2x.png ../art/ks_shift_2x.png ../art/ks_command_2x.png V Apply the style of the surrounding text to the inserted object (equivalent to the Paste and Match Style command). See “The Edit Menu.” That links to https://developer.apple.com/library/mac/documentation/UserEx..., which describes the command, too.

I disagree with the claim that this is a bad choice, though. It may not be optimal if starting from a tabula rasa, but Apple did not do that when it introduced the combination, five years ago or so, in my memory. By that time Command-V has done styled paste for about 25 years, making it difficult to dethrone.

We must be glad that we have a standard for this, not angry that it may be a bit complex to type.
