Access Service Tokens while ignoring JWT

Hello, I’m just starting utilizing Service Tokens according to the documentation right here:

https://developers.cloudflare.com/cloudflare-one/identity/service-tokens/#connect-your-service-to-access

According to that, Access generates a JWT token that I can use in the subsequent requests.

However, what if I just ignore that and keep sending the original headers CF-Access-Client-Id: <Client ID> and CF-Access-Client-Secret: <Client Secret> in all the requests?

Are there some rate limits I might face at some point? So far I haven’t noticed any.

Does ignoring JWT will create any issues for my [wordpress website](https://iccworldcupbuzz.com/), ot it is normal.
