In fact, aren't the RSA-E and RSA-S algorithms basically just historical / 
mostly deprecated in favour of marking keys for a particular use?

My impression was that many new implementations use the RSA-S and RSA-E 
algorithms for signing keys and encryption subkeys. But -- taking a look at 
SKS numbers --algorithm 1 is used quite a lot.

Having a lot of algorithm 1 makes sense: RSA-S and RSA-E are deprecated, and 
were made "SHOULD NOT" create in 4880, in favor of using the key flags 
subpacket to indicate usage.  I don't know of any current implementations that 
use RSA-S or RSA-E for new keys.
