Any defect if using armv6 ONLY in Xcode 4.2 to support both old and new devices?

I'm developing an app supporting since iOS 3.0. With Xcode 4.2, I have to add armv6 manually to Architectures. So is armv7 optimized for new devices the only advantage to compile with "armv6 armv7"? The size will be bigger than with only armv6 ?

Determining the library which causes "Illegal instruction" on a Pi Zero W (armv6), and fixing the build

I understand that a lot of compilation issues on the Pi Zeros are due to the fact that they use armv6, whereas the newer Raspberry Pi's like the 3 A+ and B+ use armv7. However, I do not understand how to find the offending library in an application…
