Is there something specifically wrong with keeping the 8 precepts as a lay person?

I know that the 5 precepts were intended for lay people. I know that in lay life, most people choose to only keep the 5 precepts, and there is no requirement to keep any more. I know that sometimes lay people take the 8 precepts temporarily. However, is there anything specifically wrong with a lay person keeping the 8 precepts on an ongoing basis? I know it's harder to do as a lay person as opposed to a novice(edit: I meant anagarika). But is it specifically discouraged or wrong for any reason?
