There's more data in termcap than that (which some people would like to use).
And there's additional data for terminfo -- again, some want it.
man infocmp:
For best results when converting to termcap format, you should use both
-C and -r. Normally a termcap description is limited to 1023 bytes.
infocmp trims away less essential parts to make it fit. If you are
converting to one of the (rare) termcap implementations which accept an
unlimited size of termcap, you may want to add the -T option. More of‐
ten however, you must help the termcap implementation, and trim excess
whitespace (use the -0 option for that).
(-T is appropriate here - ymmv)
With -C alone, I get
-rw------- 1 tom users 7315 Nov 2 21:02 .TCAP
With -CrT,
-rw------- 1 tom users 14390 Nov 2 21:02 .TCAP
For terminfo, no options
-rw------- 1 tom users 16027 Nov 2 21:03 .TCAP
For terminfo with -x
-rw------- 1 tom users 19533 Nov 2 21:03 .TCAP
