I guess manly it depends on what the recruiter values. I may see this as the equivalent of using a library and not reinventing the wheel. Something I feel is a good attitude to have as a software developer. Another recruiter may feel differently.

(I hate all the people who dogmatically tell you your CV should be this way or that, and you MUST do x in an interview. Interviewers are real people as well. Some people may value technical skills, others may prefer a cultural fit.)
