Fear of upgrading to V19

I am still on SFOS 18.5.1 MR-1-Build326 and as far as I can tell works well for me. My setup is very simple and have not used any advanced features. Everytime I upgrade firmware I basically pray that I will still have internet after rebooting. My skills are hit and miss and certainly do not have any more than a home user who does not work in tech or security. So I wonder if I can simply stick to v18.5.1 until my requirements change in the future?
