Isn't there any active plan to split formats from algorithms etc.?

Attached is a script to compare valids in different source files and its
output. Run it in the "src" dir like this:
perl valids.pl *.[ch] | LANG=C sort > valids.txt
It saves all found valids into "valids" dir and prints corresponding
filenames with files containing identical valids grouped on the same
line. It finds 166 different valids in 180 files. Grepping out only
lines containing "cuda" and "opencl" we get:
cuda_cryptmd5_fmt.c
cuda_cryptsha256_fmt.c
cuda_cryptsha512_fmt.c
cuda_mscash2_fmt.c
cuda_mscash_fmt.c
cuda_phpass_fmt.c
cuda_pwsafe_fmt.c opencl_pwsafe_fmt.c pwsafe_fmt_plug.c
cuda_rawsha256_fmt.c
cuda_rawsha512_fmt.c
cuda_xsha512_fmt.c opencl_xsha512_fmt.c
opencl_DES_fmt.c
opencl_agilekeychain_fmt.c
opencl_bf_fmt.c
opencl_cryptmd5_fmt.c
opencl_cryptsha256_fmt.c
opencl_cryptsha512_fmt.c
opencl_dmg_fmt.c
opencl_encfs_fmt.c
opencl_gpg_fmt.c
opencl_keychain_fmt.c
opencl_krb5pa-sha1_fmt.c
opencl_mscash2_fmt.c
opencl_mysqlsha1_fmt.c
opencl_nsldaps_fmt.c
opencl_nt_fmt.c
opencl_ntlmv2_fmt.c
opencl_odf_aes_fmt.c
opencl_odf_fmt.c
opencl_office2007_fmt.c
opencl_office2010_fmt.c
opencl_office2013_fmt.c
opencl_phpass_fmt.c
opencl_rar_fmt.c
opencl_rawmd4_fmt.c
opencl_rawmd5_fmt.c rawMD4_fmt_plug.c rawMD5_fmt_plug.c
opencl_rawsha1_fmt.c
opencl_rawsha256_fmt.c
opencl_rawsha512-ng_fmt.c
opencl_rawsha512_fmt.c
opencl_strip_fmt.c strip_fmt_plug.c
opencl_sxc_fmt.c
opencl_xsha512-ng_fmt.c
opencl_zip_fmt.c zip_fmt.c
So almost all gpu formats have unique valids.
