Being the go-to-person can help you, but it hinges on a lot of external factors, most of which you have limited insight on.

• What is the company’s headcount/internal hire/pay raise policy?
• Who (of importance) actually recognizes you as the go-to person?
• Of those who do recognize that, how many are aware that you are actually going above and beyond your requirements?
• Of those again, who is actually going to advocate for you, with or without you asking?

I prefer to get paid for your job twice - today for the work you’re doing now, and again for the skills/knowledge you gain that sets you apart when you job-hop. Master that tricky welding technique, get a professional certification, develop a new app, get guild/union membership, etc just find something that you can take with you.
