That is quite plausible.  I only occasionally have use for objdump, and I suspect many programmers never use it at all.  I doubt if I'd use the lto-dump version much if and when I start using LTO seriously.

What would matter for me in this case
would be a final result (exe) rather than object files. And in order to
look at exe I'd still use a normal objdump.
 

Again, I don't doubt you are correct.
All I am saying is that it does not surprise me that the lto-dump program is significantly bigger than objdump.  And presumably some people do find it useful.

The situation is not purely hypothetical. I regularly use LTCG with
Microsoft tools. Never ever I wanted to disassemble .obj files after
LTCG compilation. When occasionally I wanted to look at asm after LTCG,
it always was an exe.
