You presume a user chooses one of the approaches and uses it full time.
In that case the expose is added automatically. And what if a user
mostly uses basecurve approach and time after time wants to make a
scene-referred variant? He needs to turn off the basecurve, turn on the
filmic module (it is logical) and to add + 1EV exposure shift. The first
two actions can be done easily via custom style, but if one adds
exposure to the style, the previous exposure value will be replaced by
the value from the style (1.0). And the image will require to adjust the
exposure again.
Why can't the module itself make signal boost of +1EV at its input just
as the +1EV exposure does in the pipeline before the filmic. Is there a
difference in the results?

Filmic v4 imposes 18% scene to be remapped to 18% display no matter
what, resulting in preservation of overall brightness through the
process. Previous Filmic v3 remapped 9% scene to 18% display to better
match OOC JPEG, which creates problems with the curve (contrast
behaviour degrades if grey is not more or less centered on the graph).
Current v4 behaviour is to slide the image dynamic range along the
luminance axis with exposure module, to anchor scene grey to display
grey. Once this is done, filmic compresses the bounds of the dynamic
range by rolling *around* the grey value, used as a reference, and
therefore preserving the overall brightness of the image. This makes
the transform more predictable and remove the scene grey param in GUI,
which has confused too many users.

The change that I see in v. 4.0 is that all of my images appear 1
stop underexposed as compared to the previous version. Earlier I did
not need to adjust exposure at all, now I must boost the exposure on
all images.

Hm, as I understand, if I enable filmic plugin v 4.0 manually, I
need to
add +1.0EV manually too? That wasn't so with 3.0.

Hi,
there is a +1 EV added by default in exposure if you enable the
scene-referred workflow. I don't understand what you mean. The
exposure bias is read in image EXIF, if the bias is 0 EV, then the
setting is 0 EV too.

Hello
Exposure compensation bias for my Sony A99 is 0EV and images are too
dark. They require to add +1EV to match filmic v.3
