You could do it, but it'll hang you up every time you want to change jobs, etc. If you just want to work for yourself, and be in the same place and develop a reputation - and you're cool - it will probably work. Anywhere that will pay well and give benefits, etc wants BC. So, you can make it, but you're limited.
Thought it through because I think a huge test q10 years is BS. It's a ton of work, quite a bit of money and time, and just a huge windfall for the test writers. It's just that much more hoop-jumping.
