In digital pedal it depends on the programming, not the used processor as long as it is suitable for signal processing. You are correct that why to make single feature pedal when they can add more features easily in digital design. They doesn't need to be multi effects, but at least midi control, and several presets should be added for design just because digital can have added value.
When we talk about good compressors, they can be analog or digital, and I would check out Source Audio Atlas compressor (digital, but top design). You do not need to use all features if you don't like, but they are there for future needs. It has 6 default compressor engines even without using Neuro Editor software so most of us would find one or two to favor just by selecting presets in pedal and adjusting for taste.
